Abstract: A gaming machine which allows, according to a preset probability of
occurrence, a player to play a special game (e.g., big bonus game) more advantageous
than a normal game comprises a setting switch 46 for setting the probability of
occurrence of big bonus games at a plurality of stages, and an indicating means for
informing the player of thus set value. The indicating means comprises reel lamps
44 adapted to emit light in a plurality of light-emitting patterns while illuminating
from inside reels in a transmitting manner the symbols seen through display
windows. As the light-emitting patterns in the reel lamps 44 are changed (so as to
represent L or H) according to the set value set by the setting switch 46, the player
is informed of the setting value set by the setting switch 46. Consequently, the
player can fully enjoy games, while the profits of players and game parlors are
balanced.

Filed: 1999-04-06
Abstract: In a complimentary printing by bi-directional
scanning of a head (1) or by a plurality of heads, a
plurality of patterns in which a print start timing
is shifted by a predetermined amount are printed
with respect to a reference dot, e.g. formed by the
forward scan of the bi-directional scanning or by
one of the plurality heads (S1). In these patterns,
an area factor by the dots formed by printing of the
patterns is designed to be varied depending upon
shifting amount. An average density is read from
each of the plurality of patterns, optically (S2).
The timing at which the maximum one among average
densities read from the patterns is obtained, can be
set as the printing registration condition (S3, S4).
Further, a processing including a coarse adjustment
(S104, S105, S108)to a fine adjustment (S107, S109)
is performed in a series of algorithm. By these
processings, printing registration between a forward
and a reverse scan of a print head or printing
registration between a plurality of print heads in a
printing apparatus can be performed simply and with
high accuracy, without operating by a user.

Abstract: In a printing method which can suppress half band
irregularity caused by 2-pass printing and implement
high-image-quality printing, image data is distributed
into two sets of data for front and rear heads, and each
distributed data is distributed into two sets of data, i.e.,
forward print data and backward print data, thereby
allowing 4-pass printing. An image on one line in the main
scanning direction is formed by a total of four scanning
operations, i.e., reciprocal printing by the front head (22) and
reciprocal printing by the rear (23) printhead.

Title: Silhouette-based pose estimation
Inventor: POPA TIBERIU
IPC: G06K9/00
Filed: 2012-05-08
Abstract: Estimating a pose of an articulated 3D object model (4) by a computer is done by • obtaining a sequence of source images (10) and therefrom corresponding source image segments (13) with objects (14) separated from the image background; • matching such a sequence (51) with sequences (52) of reference silhouettes (13'), determining one or more selected sequences of reference silhouettes (13') forming a best match; • for each of these selected sequences of reference silhouettes (13'), retrieving a reference pose that is associated with one of the reference silhouettes (13'); and • computing an estimate of the pose of the articulated object model (4) from the retrieved reference pose or poses. The result of these steps is an initial pose estimate, which then can be used in further steps, for example, for maintaining local consistency between pose estimates from consecutive frames, and global consistency over a longer sequence of frames.
